Errors: Build the toolchain-gcc-9.2 version from sources on ABE framework

Hi Sir,

     I'm trying to build toolchain-gcc-9.2 version from sources on ABE framework, but it fails.

     Canadian Cross Build environment, build on x86_64-linux, host: x86_64 windows, target: ARM.

     When I refer to the Release note of how to build the toolchain from sources, I use the manifest file,but unfortunately it occured manifest format error, abe script only support1.1-1.4 version.

     Then I use the guide of abe's Canadian Cross Builds, it also occured error, I found some URLs doesn't exist.

     Can help me how to solve this problem?

      Thanks
